所以就随便搜了下Garnker的,知道是Search in Rotated Sorted Array,那题是找目标值。这里是找最小值。 我是这样想的,分为几部分, 1.如果左边的值等于中间的值了,那么就剩下两个数要判断了,而且是相邻的。 2.如果中间的值大于左边的值,那么最小值肯定不是在最左边就只在右边一块了。 3.如果中间值小于左...
Find the minimum element. You may assume no duplicate exists in the array. 本题难度Medium。 二分查找法 【复杂度】 时间O(N) 空间 O(N) 【思路】 题目假设:You may assume no duplicate exists in the array. 这道题与其他Rotated Sorted Array题一样可以用改良的二分查找法来做。 原则是只要一直...
Find the minimum element. You may assume no duplicate exists in the array. 解法1: Brute Force,直接迭代搜索。 T:O(n) 解法1: 二分法,Binary Search, T:O(logn) 显然二分法是要考察的,至于旋转数组的二分法与33. Search in Rotated Sorted Array类似。 Python: 1 2 3 4 5 6 7 8 9 10 11 12 ...
Suppose an array sorted in ascending order is rotated at some pivot unknown to you beforehand. (i.e., [0,1,2,4,5,6,7] might become [4,5,6,7,0,1,2]). Find the minimum element. You may assume no duplicate exists in the array. Example 1: Input: [3,4,5,1,2] Output: 1 ...
My code: My test result: 这不是一个好方法。下面介绍 binary search 版方法。 My code: My test result: 一下子快...
Given the sorted rotated arraynumsofuniqueelements, returnthe minimum element of this array. You must write an algorithm that runs inO(log n) time. Example 1: Input: nums = [3,4,5,1,2] Output: 1 Explanation: The original array was [1,2,3,4,5] rotated 3 times. ...

Find Minimum in Rotated Sorted Array -- LeetCode 这道题是Search in Rotated Sorted Array的扩展,差别就是如今不是找一个目标值了,而是在bst中找最小的元素。主要思路还是跟Search in Rotated Sorted Array差点儿相同。还是通过左边界和中间的大小关系来得到左边或者右边有序的信息。假设左半边有序。那么左...
Suppose a sorted array is rotated at some pivot unknown to you beforehand. (i.e., 0 1 2 4 5 6 7 might become 4 5 6 7 0 1 2). Find the minimum element. You may assume no duplicate exists in the array. 数列基本有序,则使用二分查找。假设数列是n,s是起始下标,e是最后下标,m是中...
